COMBIN ATION-STOV E.

Specification of Letters Yatent.

Patented Aug. 3, 1920.

Application filed September 30, 1919. Serial No. 327,484.

To all whom it may concern:

Be it known that I, CHARLES M. GnN'rH- NER, a citizen of the United States, residing in Reading, Berks county, Pennsylvania, have invented certain Improvements in Combination-Stoves, of which the following is a specification.

My invention relates to combination'coal, and gas or liquid fuel burning stoves, and comprises certain improvements in connection with a burner employed for heating the oven. I have provided a special form of burner which may be employed with ordinary gas, or with a gaseous vapor developed from a suitable liquid fuel, and one object of my invention is to arrange the parts so that when the valve is operated for the passage of the gas, vapor, or other burning medium, the burner will be brought into operative position, and a flame deflecting plate will be raised into proper position for cooperation with the burner in directing the flame and products of combustion to the oven in the most efficient manner. A further object of my invention is to provide means for carrying off the spent products of combustion, and a still further object is to provide a simple and compact structure and one not likely to get out of order.

These and other features of my invention are more fully described hereinafter, reference being had to the accompanying drawings, in which:

Figure 1, is a perspective View of sufficient of a stove to illustrate my improved burner structure in its relation to the oven ofsuch stove.

Fig. 2, is a cross sectional elevation on the line 11-11, Fig. 1.

Fig. 3, is a sectional plan view on the line IIIIII, Fig. 2. V,

Fig. 4, is an edge View of a flame impinging or deflector plate within the scope of myinvention and Fig. 5 is an end view showing the relation of the gas valve to the burner.

The front of the stove is indicated at l, and the oven chamber is shown at 2. Be

neath the front of the oven chamber. is-anauxiliary chamber 3, in which is located a special form of a burner f-having a series of perforations throughout its length and having at one end a mixing chamber 11.

The burner is mounted in the present instance on the gas supply pipe 5 at one end and in a bearing in the frame of the stove at the opposite end, but it may be mounted in any suitable manner.

. Pivotedto the frame of the stove at 9 is a deflecting plate 9 which is turned on its pivots on the rotation of the burner 4 which in the present instance has cam lugs 46 at each end which come in contact with the plate9 and hold it in the raised position.

On the end of-the burner is the ordinary mixing chamber having means for regulating the supply of air to the burner-6 is a gas valve having a handle 5 and on the burner is a projection 7 which is shaped as shown in Figs. 1, 3 and 5, and partly on circles the handle 5 of the gas valve and is so situated that when the handle is turned down it will be forced down, turning the burner and raising the deflecting plate 9.

The front of the stove is'preferably provided with an aperture 10 affording access to the chamber 3 to permit ignition of said burner, and has a series of perforations 12 for a secondary supply of air.

The deflecting plate 9 which is pivotally mounted at 9 in the bottom of the oven, lies flat when the gas burner is not in'use; and rests upon a shelf 9 formed in connection with the bottom plate of the oven.

' Preferablythe deflecting plate comprises two sections of thin metal, 9 and 9 spaced apart as indicated in Fig. 4; one plate havingspacing lugs 13. The plates'may be secured together by bolts or screws 14.

The oven plate or grid 15-is preferably provided with a solid portion 15 which is adjacent the deflecting plate 9 when the latter is in'the raised position, as clearly shown in Fig. 2, so as to extend the deflecting surface, and beyond this point the plate 15 is aperturcd, as at 15 so that the prod nets of combustion may rise' through the same. and circulate in the oven.

At the rear of the burner, (looking from the front), the shelf 9 of the bottom plate of the oven is perforated at 17 for egress of products of combustion afterheating the oven, and through such perforations the spent products of combustion may pass to T the soot-collecting chamber 18 below the bot tom plate of the oven, and any accumulationmay be removed through a small opening l9,normally closed by a door 19 at the front of the same. The passage of the spent products of combustion through the perforations 17 is in front of the burner flame and without affecting the same.

When the gas valve 6 is closed by turning the handle 5 the burner is turnedon its pivot by the weight of the deflecting plate 9the plate closes theopening in the hottom of the ovenand may be weighted, so as to readily close and also turn the burner.

Fig. 1, it will be noted, shows the lugs 4 in two positions; the dotted lines show them in substantially the normal position, and the broken lines show. them in the position they meaning thereby the use of ordinary com-- assume to hold the pivoted deflecting plate in the raised position. I

While reference is made to a gas burner,

mercial-gas, itwill be understood that my improved structure may be used with natural gas, and that any form of structure wherein liquidfuel is turned into a. gaseous vapor may be employedin connection with my im- 7 proved burner and the operatlng, means therefor, and the cooperating parts.

Iclaim: I 1. The combination in a stove, of a pivoted burner structure, a valve controlling the flow of gas to the burner, a flame deflecting platelocated above the burner and means actuated by the valve for turning the burner and elevating the deflecting plate when gas to the burner, the burner will be turned on its pivot and will elevate the deflecting plate.

, 3. The combination, in a stove, of a chamber at the front ofthe same below the oven; the front plate having air inlets communieating with said chamber, a burner located in said chamber, a valve controlling the supply of a burning medium to said burner,

means carried by the burner for engageinent by the valve when the latter is turned to open position to rock or turn said burner, a pivotally mounted flame deflector forming the top of said chamber, and means whereby the flame deflector may be turned on its pivots to raise-the rear edge for the passage of flame when the burner is turned upon opening the valve.

4. The combination, in a stove having a chamber at the front of the same below the oven, of a front plate having air inlets communicating with said chamber, a burner located in said chamber, a valve controlling the supply of a burning medium to said burner, an operating handle for said valve, a projection carried by the burner for engagement by the valve operating handle when the valve is turned to open position to turn said burner, a pivotally mounted flame deflecting plate forming the top of said medium to said burner,-a projection on the burner located in the path of the valve handle, a pivotally mounted flame deflecting plate forming the top of said chamber, and

cams carried by the .burner and engaging said flame deflecting plate whereby the latterv may be turned on its pivots to raise the rear edge for the passage of flame when the burner isturned.

6. The combination in a stove, of a chamber at the front of the same beneath the even, a flame deflecting plate covering the chamber when gas is not used,a burner located in the chamber under the plate and a cam on the burner arranged to raise the plate when the burner is turned and a gas supply pipe for the burner having a hand operated valve, said burner having a portion arranged to be engagedby the valve when turned to the open position.

7. The combination, in a stove, of a chamber at the front of the same beneath the oven, a plate pivotally mounted and covering said chamber when not in use; said chamber having a shelf upon which said plate may rest, a burner located in said chamber, a valve, cooperating means between the valve andburner whereby the latter may be turned or rocked when the valve is opened, andmeans carried by said burner for turning the plate on its pivots when the 7 burner is rocked or turned in its bearing; said shelf upon which the plate rests hav-V ing apertures for the circulation of heat and products of combustion when the plate is in the raised position.
